14f Gbtoznaw v so t at it has been necessary to switcher haustedthrough'a pipe 33 in a well knownv I The piston rod 25 carries cross- 4Oat th' when the caris to be'ooupled in a train the means considerableswitching and turning of the car will be avoided, since with thiscoupling and draft gear-it is unnecessary to have the car at the .end ofthe train, except when it is-to be dumped.-

Heretofore, cars dum ing at one end only have been used, and suc carshave not been equi ped with couplings at the dumping end turn these carsaround considerably in order to get the dumping end at the rightposition. With this construction herein, it is possible to avoid allthis switching and turning inasmich as the car can be coupled fromeither on 1 The upright side frames 1 each have a shelf 13 onwh ch" ismounted a bracket 14 having a horizontaltrack 15 on which trun nions 17connected 'w-ith the car body 7, as by a yoke 18, roll. The brack-ets 14also have racks 1 9 on which roll gears 20 keyed to the trunnions 17, sothat as the body is moved lon itudin-ally of the car frame, itsimultaneous y tilts. In order to actuate the car body, a power cylinder23 is provided, having a piston 24 and 'a piston rod 25 connected by astrap 26 with one of the tr'unnions 17. As shown in Fig. 1, the car bodyis at its upright central osition and the iston 24 midway of the cyinder 23, and a our-way valve 31 admits pressure throu h one orthe otherof pipes 27 or 28 to one si opens the other side to the exhaust. To movethe car body the fluid pressure may be admitted by means of an i et 32and is exmanner. v head 29 which straddles'one of the racks 19 andslides on a guideway 30 (F 4 As shown in Fig. 1, it will be observe d.that cylinder 23, having a length equal to the/total movement of the carbody, may be so'long as to interfere with the dumping'of the car body tend, or require lengthening of the frame in order to attach the draftbar8.

, In 'order to permit of shortening the car frame, and also decrease theweight, the mechanism shown in Fig. 2 may be used. In this figure, thearts other than those shown will be exactly e' his 1 save that thesideframes-l at the cylinder end may be somefln'l ig. 2, the iston rod 25 ismade'hollotg aiid has a cross ead 28 fixed thereto as in ,ml'. [Betweenthe rod'25 and the strap 2% in .L igtks interposed a sup lementaiy'additional'sn'ction of piston roo 35 having shoulders '36 out thereinat adistance apart equal to the longitudinal distance the 'car body willmove in going from its central position to its extreme outwardposition-in either direction. The end of'the rod 25 is threaded andcarries. a nm 38 thereon." Mounted to'embrece the nut and toextend e ofthe piston and assess in the one or the other of the slots 36 is adivided collar 39 held by bolts 40., By releasing the bolts 40 andremoving the collar 39, the piston rod 25 and the strap 26will bedisconnected. if now steam or, air be admitted on the right side of thei'sto'n 24 in Fig. 2, it will be moved towards t e left with-v outmoving the stra 26 or the rod 25. As

e rod 25 goes over the soon as the end of t left hand'shoulder 36 on therod 35, the

piston 24 will be at or about the extreme left end of the cylinder andthe collar 39 can be replaced, thereby again coupling the piston rod 25and the rod 35, and making the piston rod longer than it was beforei Ifbe now admitted behind the piston 25 at the left end of the cylinder,the car body will be moved and dumped towards the right end of the frameand can be brought back to central position by reversing the pressure.In order to dump to-the left the'piston rod will be 1 shortened' Fi 2shows this condition in which the car ody will be dumped to the leftwhen pressure is admitted: at the right end of the cylinder. The sideframes are provided with stops 42 at the left end against which thetrunnions 17 will similar stop l3 is provided on the left or cylinderend, on the sideopposite the cylinderto check the movement in thatdirection. At the same time that the trunnions l7 strike the stops 42 or43, the lower side of the car body will rest on the endirame 6 as shownin dotted lines in Fig. 1, so that the car body will be positivelystopped at separated oints to have the piston stri e the without tendingend of the cylinder. In practice, suitable latches or mechanical lockingdevices may be used to hold the car body in upright position duringtransportation.

From the fore seen that a doub e end dumpmg car is'provided which may bemounted on a single truck, by reasonof its shortness between couplings,and which will not tend to be pulled off the track in oing aroundcurves, as happens where the ame has too great an overang beyond the"wheels. Also, it is pos-. sible to construct short frame by reason ofthe underframe 2h body, and also supporting'the car bod -at. either end,in dumpedpositiorr. It will of course 'be understood that the dimensionsof the frame and-side hi the ladle will be determined according to therequirements 'of actnal also order to permit the car body toclear.

Whilea motor is herein shown mounted on the frame for operating the carbody, it is not to be understood that the'invention is limited to motormeans for operating the car body inasmuch as manual devices canv bepractice, and in some instances it may 'mounted on the frame hereindescribed for operating the car body. Such operating depressuretendingunder the car necessary to flare the side frames in' strike, and a c v nI c oing description, it will be tron.

Various modifications and changes in the specific construction hereindescribed may be made without departing from the scope of the invention.
